Sorry to hear about the trouble. Is this the first time you installed Quik for Desktop in your computer? Or were you able to get the thumbnails working before? When did this issue started from happening?

Ensure to have Windows and your graphics card drivers updated to the latest version

Do the thumbnails appear black as well on your Windows file explorer screen? See if uninstalling and re-installing the app will help. Please also test with newly-captured files and check if the thumbnails will still appear black.

Thank you for the reply, @royalvista52205. The ELECOM 64GB microSDXC1 is not among the recommended cards on this list, and it might be causing the issue. Do you mean that you have new files on the SanDisk Extreme 16GB microSDHC1 and they do not show the thumbnails as well? Will you be able to test how it goes with a recommended SD card? Many thanks!
